I was wondering if there is a way I can mix the two and put it in a spray bottle? I would like to use water + baking soda in some cases to spray a little rather than have large amounts. Is it possible? I've tried, but the nozzle always ends up clogged.
Baking soda is soluble in water at up to 90 grams per liter. If you add more than that to water, you'll end up with a saturated solution at 90 g/L plus some crystalline baking soda on the bottom of the container.
A teaspoon of baking soda has a mass of about 4.8 grams, so it'll take 53 ml of your saturated soda solution to deliver 1 teaspoon baking soda. In Fully metric terms, that's 11.1 ml of solution per gram baking soda.
I really have no idea why you'd need to do this for cooking. The amount of baking soda in solution in a few sprays of a bottle is going to be tiny. If this is actually cooking related, I'm sure there's a better way.
But if there's some use for your spray bottle of solution, you probably just need to clean the nozzle periodically - spraying plain water through it now and then would work. Nothing's going to stop the water in the nozzle from evaporating, though.
A small pot of water and baking soda (over saturated is OK), and a simple brush is all you need
A quick stir of the pot with the brush, and wash it on what you need works fine
I’m asking because I’ve read that Evian water with 360 (not stated) bicarbonate make great coffee. I bought some for my espresso machine and it’s very good. So, I’d like to add how much baking soda to a gallon of water. Thanks for any help.
